Fabrication of Levothyroxine Particles Encapsulated with Apatite

Article Preview

Abstract:

Apatite nuclei were obtained by raising pH of an acellular simulated body fluid (SBF). The apatite nuclei and levothyroxine particles were dispersed in an ultrapure water and the apatite nuclei were attached to the surface of the levothyroxine particles. By soaking in SBF, apatite formation was induced by the apatite nuclei located on the surface of the levothyroxine particles and the levothyroxine particles were encapsulated with apatite. We evaluated release behavior of levothyroxine in phosphate buffered saline.
